In the project described by How-To Geek’s September 28, 2026 article excerpt, the Pi checks weather hourly, uses Open-Meteo for data and Ollama to run a language model locally. The model’s melody is saved as JSON. The excerpt does not provide the full code or enough hardware and software details to reproduce that exact build, but its design offers a clear blueprint for a similar project.
How the weather-to-music pipeline works
The key is to keep weather interpretation separate from music generation. Weather does not directly dictate every note: explicit rules first reduce conditions to a musical mood, and that mood guides the model’s composition.

- Get current weather. The described project checks conditions once per hour using Open-Meteo. Its article excerpt says the weather check is the part that requires an internet connection.
- Choose a mood. A plain-text mapping connects conditions to musical character. Examples given are sunny weather to joyful music, rain to sombre music, snow to delicate music, and storms to tense music.
- Generate a melody. Ollama runs a small language model locally on the Pi. The mood rules shape musical choices such as tempo, instruments, and register; the model returns melody data in a JSON file.
- Play the result. The Pi turns the generated musical material into audible output. The excerpt does not identify the software or hardware used for that step.
This division of work matters: the weather source supplies conditions, the mapping makes the result predictable and legible, and the model supplies variation within the chosen style. Without explicit rules, a model might produce a musical response that does not reliably reflect the weather.

The named elements in the described project are a Raspberry Pi, Open-Meteo, Ollama, a local language model, a weather-to-mood mapping, and a way to play the composition. The source excerpt does not name the Pi model, model name or size, synthesizer, playback software, speaker, or wiring. Treat those as choices for your own implementation rather than established parts of the original build.
#1 Best Overall
- Includes Raspberry Pi 4 4GB Model B with 1.5GHz 64-bit quad-core CPU (4GB RAM)
- Includes Pre-Loaded 32GB EVO+ Micro SD Card (Class 10), USB MicroSD Card Reader
- CanaKit Premium High-Gloss Raspberry Pi 4 Case with Integrated Fan Mount, CanaKit Low Noise Bearing System Fan
- CanaKit 3.5A USB-C Raspberry Pi 4 Power Supply (US Plug) with Noise Filter, Set of Heat Sinks, Display Cable - 6 foot (Supports up to 4K60p)
- CanaKit USB-C PiSwitch (On/Off Power Switch for Raspberry Pi 4)
- Weather input: use an online weather source such as Open-Meteo, which the excerpt describes as needing no key or account, or collect measurements with local sensors.
- Composition logic: define a small, explicit set of weather-to-mood rules and decide what each mood means for tempo, register, and instrumentation.
- Generation: the project uses a model running locally through Ollama and writes melody data to JSON. The excerpt does not specify the output schema or how that data is rendered into sound.
- Audio output: choose an output route suited to your setup. Raspberry Pi OS documentation describes audio playback and options including USB speakers and other audio interfaces; its audio documentation also covers Audio HATs for different output needs. These are possible routes, not confirmed components of the project. See Raspberry Pi OS documentation and Raspberry Pi audio documentation.
For a desktop setup, Raspberry Pi OS includes VLC and supports playing audio. A headless or embedded build may use a different software path. Raspberry Pi OS editions differ: desktop editions include a graphical interface, while Lite is command-line-only and intended for headless or embedded use. Check the current OS and Python packaging guidance before installing software; the article excerpt does not give version-specific setup instructions.
Choose between online weather and local sensors
The project excerpt uses an online weather check and mentions an ESP32-based DIY weather station as an alternative. The choice changes what the music represents: an online source supplies reported weather for a location, while local sensors can reflect conditions measured where the device is installed.

| Weather path | What it provides | Trade-off |
|---|---|---|
| Online weather data | Weather information retrieved over the internet; the excerpt names Open-Meteo for the project. | The check depends on an internet connection. The excerpt does not specify an endpoint, query parameters, or location configuration. |
| Local weather station | Measurements from sensors installed at or near the Pi; the excerpt mentions an ESP32-based DIY station as an alternative. | Requires sensor hardware and a way to pass measurements to the Pi. The excerpt does not describe the station’s sensors or integration. |
Raspberry Pi’s weather-station and related project resources offer a broader starting point for local-sensor projects. They do not establish that the music project uses a Raspberry Pi weather-station kit.

The article excerpt establishes the concept and names its weather service and local model runtime, but it is not a complete build guide. It does not disclose the Pi model, local model identity or size, exact API request, full source code, JSON format, synthesis method, playback program, speaker, wiring, or power requirements. As a result, you can reproduce the architecture from the description, but not the exact build without those implementation details.
